Jeff I've spend many hours working through the issues you brought up (indeed cache management, population, and security are three of my focus areas in LISP, and something we considered when we started this), have been socializing them with the LISP team, and can personally say that I take your comments very seriously.  Or testing group in house as well as on the LISP beta network have been working through these issues.  Also, we've had an email thread going on about this for, by my count, 3-4 replies back and forth.

While I appreciate your opinions above, I have to say that I disagree with them, and also with the conclusions you draw.

P.S. oh and Randy Bush is pretty damn smart. :-)
